The sections B are made of twovgenerally anr traight sections of thestove whenyused, and having gle-shaped piecesi'of comparatively thinsheet metaLibentat their middle to provide a corner "7 f'e'xtendingrectangularly "therefrom, providing the diverging walls 858. 1 Suchangle-shaped sec; tions are of suitable length and adapted to makeabutting Qengagemen't', V with each "other, or are preferably)bentlinwardly at one end, as at 9",'-t o make sliding telescopingengagement {with the '[opposite'end oi the n'extsection, as in Fig.3.

The construction and operation of the invention will be readilyunderstood from the foregoing description. It may be applied to anyexisting stove pipe by application of the successive pairs of bands 10,which are amply flexible to permit opening around the pipe by removal ofthe nuts of screwsmr bolts,. 1 1, then bringing the ends togather anmitighte'ning pla ce; ighe successive outer sections are then applied, sothat the entire pipe becomes covered.
